Specific embodiment
Fig. 1 to Fig. 7 illustrates the embodiment of the floor air conditioner using the air condition of that present invention air channel structure.
As shown in figs. 1,2 and 6, air-conditioned wind tunnel mechanism of the invention, including inlet section 10, heat exchanging part 20, outlet air
Portion 30.
Inlet section 10 includes fluidic generator 102, air intake passage.
Fluidic generator 102 provides high-speed flow and flows to heat exchanging part 20, and in inlet section 10 under the action of jet effect
Inside forms low-pressure area, and external air flow flow to heat exchanging part 20 from the air intake passage under differential pressure action；External air flow is described
Heat exchanging part 20 is completed to flow out air conditioner from the outlet section 30 after exchanging heat.
As shown in fig. 6, principle of the fluidic generator 102 according to jet effect, is provided less by compact pump is (not shown)
Compressed air is measured as power source, sprays to form primary airstream by inner annular nozzle at a high speed, this strand of primary airstream is adsorbed on
The surface of profile, an and low-pressure area is generated inside inlet section 10, cause around a large amount of air be inhaled into, primary airstream and week
Enclose after air-flow converges formed high speed, high capacity air-flow along spray nozzle front end spray, flow to heat exchanging part 20.
Since the air flow drive device of the air-conditioned wind tunnel structure replaces tradition to use fan blade type using fluidic generator 102
Blower avoid the noise generated when fan blade air-supply, while also optimizing the total coating process of air-conditioning due to eliminating fan blade,
Improve production efficiency；And the application of jet effect also improves the efficiency of air-conditioning, keeps the use of air-conditioning more energy saving, easypro
It is suitable.
Preferably, as shown in Figure 2, Figure 4 shows, the air intake passage of inlet section 10 includes primary afflux portion 101, secondary afflux portion
103；First end of the fluidic generator 102 far from heat exchanging part 20 is arranged in primary afflux portion 101；The secondary setting of afflux portion 103 exists
Second end of the fluidic generator 102 close to heat exchanging part 20.
The side wall in primary afflux portion 101 and the side wall in secondary afflux portion 103 offer multiple to be flowed into for external air flow
Through-hole.The junction being arranged between primary afflux portion 101 and secondary afflux portion 103 due to being distributed in fluidic generator 102, institute
After projecting high speed compression air-flow with fluidic generator 102, low-pressure area is formed inside inlet section 10, extraneous air is made in pressure difference
The through-hole that the side wall of side wall and secondary afflux portion 103 under from primary afflux portion 101 opens up flows into air conditioner, completes air inlet.
By the setting of above structure, the space at 102 both ends of fluidic generator can be made full use of to complete air inlet, make inlet section 10 into
Wind space is bigger, more efficient.
Preferably, as shown in Figure 2, Figure 4 shows, through-hole on primary 101 side wall of afflux portion from close to fluidic generator 102 to
It is arranged from big to small on direction far from fluidic generator 102, i.e., the aperture of the through-hole in primary afflux portion 101 is closer to jet stream
Generator 102 is bigger.
Through-hole on secondary 103 side wall of afflux portion is in the side from close to fluidic generator 102 to far from fluidic generator 102
It arranges from big to small upwards, i.e. the aperture of through-hole in secondary afflux portion 103 is bigger closer to fluidic generator 102.
By the design of above structure, the jet stream gravitation at the fluidic generator 102 can be made full use of bigger, affect sky
The characteristics of gas is more obvious, it is ensured that while air intake space abundance, it is ensured that the through-hole far from fluidic generator 102, which is reduced, to be scattered and disappeared
The energy of air-flow improves the efficiency of air-conditioning air inlet, also plays certain effect to preventing foreign matter from entering inside air-conditioning.
Further, as Fig. 6,7, fluidic generator have the annular semi-enclosed cavity of nozzle 104, the semiclosed chamber of annular
The radius of the place circle of the bottom of body is less than the radius of circle where top.Nozzle 104 is by the inner wall of annular semi-enclosed cavity and outer
Wall surrounds, and is placed in the export direction of the bottom of annular semi-enclosed cavity and nozzle towards top.Nozzle 104 is by the semiclosed chamber of annular
Body interior is gradually reduced, and the inner and outer wall minimum spacing of nozzle is 1-3mm.
Further, as shown in Fig. 2, Fig. 3, Fig. 5, the heat exchanging part 20 of the air-conditioned wind tunnel structure include radome fairing 201,
Outer cover 202, heat exchanger 203, seal closure 204.The air-flow that heat exchanging part 20 is arranged in radome fairing 201 flows into end, the gas of radome fairing 201
Stream guide surface is fairshaped conical surface 201a.Heat exchanger 203 is cylindric or polygon tubular.The setting of seal closure 204 is exchanging heat
Between portion 20 and outlet section 30, the air-tightness of air-out passage is promoted.
Fairshaped conical surface 201a on radome fairing 201 can smooth guidance air-flow lead to by heat exchanger 203 and outer cover 202
Air duct made of common limitation, air-flow are worn to the inside sidewalls of heat exchanger 203 from 203 side-wall outer side of heat exchanger and are exchanged heat, then
Outlet section 30 is flowed to by the air-out passage constituted inwardly with outlet section 30 in the week of heat exchanger 203, completes outlet air.Above-mentioned design,
It wears exchange heat to the side-wall outer side of heat exchanger 203 from 203 inside sidewalls of heat exchanger relative to air-flow and has better effect, because
Air-flow after heat exchange will not be contacted directly with the outer cover 202 of air conditioner heat exchanging part 20, and outer cover 202 will not generate supercooling or overheat
Phenomenon, to promote the comfort that air conditioner uses.
Preferably, as shown in figure 5, radome fairing 201 can be convenient close to the fluted 201b of the end face of heat exchanger 203 setting
The air conditioner condensed water that heat exchanger 203 generates in refrigeration is collected and discharged, condensed water is avoided to produce air bottom electrical component
Raw damage or outflow air conditioner bring inconvenience.
To sum up, the floor air conditioner using air-conditioned wind tunnel structure of the invention is compact-sized, can achieve air conditioner drop
It makes an uproar, improves the efficiency of air-conditioning, reach the technical effect for promoting air-conditioning comfort.
Air-conditioned wind tunnel structure of the invention uses the embodiment party in floor air conditioner above described embodiment only expresses
Formula, the description thereof is more specific and detailed, and but it cannot be understood as limitations on the scope of the patent of the present invention.It should be understood that
It is that for those of ordinary skill in the art, without departing from the inventive concept of the premise, several deformations can also be made
And improvement, these are all within the scope of protection of the present invention.Therefore, the scope of protection of the patent of the present invention should be with appended claims
